Take a Virtual Tour of NASA

Welcome to NASA! Today, we’re taking you behind-the-scenes for a virtual tour looking at our cutting-edge work and humanity’s destiny in deep space!

Starting at 1:30 p.m., we will host a series of Facebook Live events from each of our 10 field centers across the country. Take a look at where we’ll be taking you…

Glenn Research Center 1:30 p.m. EDT

Our Glenn Research Center in Cleveland, OH will host a tour of its Electric Propulsion Lab. This lab is where we test solar propulsion technologies that are critical to powering spacecraft for our deep-space missions. The Electric Propulsion Laboratory houses two huge vacuum chambers that simulate the space environment.

Marshall Space Flight Center 1:50 p.m. EDT

Our Marshall Space Flight Center in Huntsville, AL will host a tour from a Marshall test stand where structural loads testing is performed on parts of our Space Launch System rocket. Once built, this will be the world’s most powerful rocket and will launch humans farther into space than ever before.

Stennis Space Center 2:10 p.m. EDT

Our Stennis Space Center in Bay St. Louis, MS will take viewers on a tour of their test stands to learn about rocket engine testing from their Test Control Center.

Armstrong Flight Research Center 2:30 p.m. EDT 

Our Armstrong Flight Research Center in Edwards, CA will host a tour from their aircraft hangar and Simulator Lab where viewers can learn about our X-Planes program. What’s an X-Plane? They are a variety of flight demonstration vehicles that are used to test advanced technologies and revolutionary designs.

Johnson Space Center 2:50 p.m. EDT

Our Johnson Space Center in Houston, TX will take viewers on a virtual exploration trip through the mockups of the International Space Station and inside our deep-space exploration vehicle, the Orion spacecraft!

Ames Research Center 3:10 p.m. EDT

Our Ames Research Center in California’s Silicon Valley will bring viewers into its Arc Jet Facility, a plasma wind tunnel used to simulate the extreme heat of spacecraft atmospheric entry.

Kennedy Space Center 3:30 p.m. EDT

Our Kennedy Space Center in Florida will bring viewers inside the Vehicle Assembly Building to learn about how we’re preparing for the first launch of America’s next big rocket, the Space Launch System (SLS) rocket.

Langley Research Center 3:50 p.m. EDT

Our Langley Research Center in Hampton, Virginia will bring viewers inside its 14-by-22-foot wind tunnel, where aerodynamic projects are tested.

Goddard Space Flight Center 4:10 p.m. EDT

Our Goddard Space Flight Center in Greenbelt, MD will discuss the upcoming United States total solar eclipse and host its tour from the Space Weather Lab, a large multi-screen room where data from the sun is analyzed and studied.

Jet Propulsion Laboratory 4:30 p.m. EDT

Our Jet Propulsion Laboratory in Pasadena, CA will bring viewers to the Spacecraft Assembly Facility to learn about robotic exploration of the solar system.

So, make sure to join us for all or part of our virtual tour today, starting at 1:30 p.m. EDT! Discover more about the work we’re doing at NASA and be sure to ask your questions in the comment section of each Facebook Live event!

In Case You Missed It...

NASA astronaut Jessica Meir sat down and answered your questions during a Tumblr AnswerTime session! 

But don’t worry, we’ve got a recap for you! In addition to the highlights below, you can check out the full AnswerTime here. 

Astronaut Jessica Meir was selected as part of our 2013 astronaut class (which was 50% women!) and is currently training to go to space. She could be one of the first astronauts to ride in the Orion spacecraft, which will carry humans deeper into space than ever before. 

Let’s check out some of her responses...

One Year Later

On March 1, 2016, veteran astronaut Scott Kelly returned from his Year in Space mission. In many ways, the adventure was just beginning.

The spaceflight part of the One Year Misson to the International Space Station ended a year ago today, but the science behind it is still moving. Astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko continue to provide samples for the data collection from their ground-breaking mission. Results are expected to to start coming later in 2017, which will help launch humanity on deep space missions.

Kelly not only commanded the International Space Station’s Expedition 46, he participated in spacewalks like this one on Dec. 21, 2015, in which Kelly and astronaut Tim Kopra successfully moved the Space Station's mobile transporter rail car ahead of the docking of a Russian cargo supply spacecraft.

On the station in 2015, Kelly showed off his home away from home. Scott tweeted this image out with the comment: "My #bedroom aboard #ISS. All the comforts of #home. Well, most of them. #YearInSpace." 

Why was the Year In Space important? As we work to extend our reach beyond low-Earth orbit, how the human body reacts to microgravity for extended periods is of paramount importance. Not only were Kelly and his Russian counterpart monitored throughout the mission, they both continue to submit to tests and monitoring one year later to see if there are any lasting effects from their voyage aboard the station. 

Scott Kelly also a human control here on Earth, his identical twin brother and fellow astronaut Mark Kelly. Both brothers have served aboard the International Space Station, but Scott’s stay was almost twice as long as typical U.S. missions. The continuing investigations are yielding beneficial knowledge on the medical, psychological and biomedical challenges faced by astronauts during long-duration spaceflight.

The One-Year Mission

First off, what is the One-Year Crew? Obviously, they’re doing something for a year, but what, and why?

Two crew members on the International Space Station have just met the halfway point of their year in space. NASA Astronaut Scott Kelly and Russian Cosmonaut Mikhail Kornienko are living in space for 342 days and will help us better understand the effects of microgravity on the human body.

Why 342 days and not 365? Thought you might ask. Due to crew rotation schedules, which involve training timelines and dictate when launches and landings occur, the mission was confined to 342 days. Plenty of time to conduct great research though!

The studies performed throughout their stay will yield beneficial knowledge on the medical, psychological and biomedical challenges faced by astronauts during long-duration spaceflight.

The weightlessness of the space environment has various effects on the human body, including: Fluid shifts that cause changes in vision, rapid bone loss, disturbances to sensorimotor ability, weakened muscles and more.

The goal of the One-Year Mission is to understand and minimize these effects on humans while in space.

The Twins Study

A unique investigation that is being conducted during this year in space is the Twins Study. NASA Astronaut Scott Kelly’s twin brother Mark Kelly will spend the year on Earth while Scott is in space. Since their genetic makeup is as close to identical as we can get, this allows a unique research perspective. We can now compare all of the results from Scott Kelly in space to his brother Mark on Earth.

But why are we studying all of this? If we want to move forward with our journey to Mars and travel into deep space, astronauts will need to live in microgravity for long periods of time. In order to mitigate the effects of long duration spaceflight on the human body, we need to understand the causes. The One-Year mission hopes to find these answers.

Halfway Point

Today, September 15 marks the halfway point of their year in space, and they now enter the final stretch of their mission. 

Here are a few fun tidbits on human spaceflight to put things in perspective:

1) Scott Kelly has logged 180 days in space on his three previous flights, two of which were Space Shuttle missions. 

2) The American astronaut with the most cumulative time in space is Mkie Fincke, with 382 days in space on three flights. Kelly will surpass this record for most cumulative time in space by a U.S. astronaut on October 16.

3) Kelly will pass Mike Lopez-Alegria’s mark for most time on a single spaceflight (215 days) on October 29.

4) By the end of this one-year mission, Kelly will have traveled for 342 days, made 5,472 orbits and traveled 141.7 million miles in a single mission. 

Have you seen the amazing images that Astronaut Scott Kelly has shared during the first half of his year in space? Check out this collection, and also follow him on social media to see what he posts for the duration of his #YearInSpace: Facebook, Twitter, Instagram.
